Incorrect, the Toshiba (and so far all HD DVD players) always
decode all audio on HD DVDs. They do that so menu sounds and other interactive audio can be mixed with the movie soundtrack.
If you choose S/PDIF on the Tosh (or the 360), then that decoded and mixed audio has to be encoded (compressed) into a format that can be passed over S/PDIF, full-bitrate DTS in the case of the Tosh, full-bitrate DD in the case of the 360.
The receiver is just interpreting DD+ as DTS because of the higher bitrate.
No, the reciever is recieving DTS, if it were getting DD+ (which can't be sent over S/PDIF btw), it wouldn't know what to do with it. And it would say nothing, or you'd get static out your speakers.
This was discussed way back when it first came out. Since none of the receivers are capable of decoding DD+ it can't display it as decoding DD+, it recognizes it as DTS.
True there are no recievers capable of decoding DD+, but they display DTS, because that's what they recieve, because that's what the Tosh outputs over S/PDIF.
DD+ (as well as DTHD and DTS-HD) can only be passed over HDMI 1.3, the Tosh doesn't have HDMI 1.3. S/PDIF only support DD and DTS (and stereo PCM) nothing else can be passed over S/PDIF.
